R help - Oct 2003 - Saving workspace image

Hi folks,

On quitting R with q(), is it possible to save the workspace
to a directory other than the one R was started from?

(I sometimes have a project "master" directory with the major
R code and data in that directory, but divisions of the project
having their specific stuff in sub-directories. So if I quit while
running a sub-project, I'd like to save the workspace back into its
sub-directory. I see that this could be achieved by starting R in that
sub-directory, and invoking "master" code as
source("../whatever"),
but this would be a lot less convenient than doing it the other way
round).

With thanks,
Ted.

Ted,

Use:

setwd("PathToDir")

prior to quitting. That will set your working directory.

Alternatively, you can always use:

save.image("PathToDir/.RData")

to save the workspace image explicitly where you want it.

See ?setwd and ?save.image
